Experiments were performed to evaluate a recent extraction process called the instantaneous controlled pressure drop process (briefly: DIC process: “Détente Instantanée Contrôlée”) for extracting some volatile compounds from red cedar wood. T

The effects of thermo-compression on the physical properties such as bulk density, mass yield, surface area, and also adsorption capacity of activated carbon were studied. The activated carbon samples were prepared from thermo-compressed and virgin f

The aim of this work was to characterise the activated carbon produced from wood and its basic components: cellulose, lignin and xylan (hemicelluloses). Two ways of activation were tested: simple pyrolysis under N2 and thermal treatment of the materi

The objective of this study is to assess the uptake of hexavalent chromium (Cr(VI)) from aqueous solutions onto activated carbons (AC) produced from wood. Two activated carbons are tested, a KOH-activated carbon and a commercial H3PO4-activated carbo

The kinetics of pyrolysis of a micro-crystalline cellulose in nitrogen were studied from TGA and DTG data, obtained with two different modes of heating: a dynamic mode at constant heating rates between 1 and 11 °C/min and an isothermal mode at vario

The purpose of this paper is to describe a process of wood liquefaction in two steps: a first step of wood solvolysis in acidified ethylene-glycol or in some recycled solvent; a second step of catalytic hydrogenation at high pressure of the solvolysi

The purpose of this study was to evaluate the amounts of various pyrolysis products (gases, water, tar and charcoal) from three biomasses (wood, coconut shell and straw) and to suggest a kinetic equation for the thermal cracking of tar at temperature

From the shape of stationary profiles of temperatures and moisture for the gas and solid phases, two distinct zones clearly appears in a counter-current cascading rotary dryer of sugar; a first zone in which the drying takes place, a second zone in w
